Our invention relates to anew construction for wall openingV frames andsash including door and window frames 'and certain strips for detachablysecuring window panes; The objectv of the invention is to provide asimple and eiiicient frame construction entirely of comparativelyA lightsheet metal and involving elongated hollow strips to serve as dooryframes,'window sash i and window pane parting strips according tothe'size of strips, asrshown in the accompanying drawing'7 in `whichvFig. 1'is afaoe view of a portion of a wall with a door and vwindowembodying our 1 improved construction.

F 2 is an elevationV of a window of our improvedtype.

Fig. 3 is an enlarged detail sectional .View as on line 33 in Fig. 1showing one form i? of our device as a parting strip for window panes. Yv

Fig. 4 is an enlarged sectional view about as on line 4-4 in Fig. 1.

Fig. 5 is an enlarged cross section of a door and adjacent parts aboutas on linel 5 5 in Fig. 1.

Figs. 6 and 7 are modifications of our device in cross section as usedfor a door frame.

' Referring to the drawing by reference numerals 1 designates a wallhaving a window 2 and a door 3.

Our improved frame and strip construction is embodied mainly in a sheetmetal tube of approximately a fourepoint st ar shape in cross section asthe tube 4 in Fig.

4, in which the sheet metal edges are over' lapped as at 4X and suitablywelded or Otherwise held together. The points of said star shaped tubeare preferably tapered g outwardly from the center7 said pointshereinafter being designated as 4A, 4B, 4C and 4D and at the convergenceof said arms the metal is preferably rounded as shown. This constructionas described and hereinafter p set forth in various modified forms andsizes can be used as a door frame, window frame, windaw sash and windowpanel strips.

In Fig. 4 one form of our strips is shown as a window sash Or theperimetral frame of a slidable window. In this form the strips are cutyas required and miteredl to fit together at' the corners and besuitably welded or joined as at 10 in Fig. 2. The inwardly directed armsA4D are acommon plane and against which the pane 51s laid and anauxiliary sheet metal strip'l of L-'shape in cross sectionlis laidagainst'the opposite side ofthe glass'f5, one arm or edge of lsaidauxiliary strip being hooked as '6^ and adapted yto engage the outeredge of arm 4C.

This auxiliary strip 6 is secured' to the tubular strip .4 .byl beingprovided with apertures 6B- through each of which a machine Screw 7 ispassed through the central part of tube 4 diagonally and provided withuawnut 8 at the Opposite side. Thus Va complete single-'pane sash ismade and the outward arm 4A of the vertical tubes are slidable orfixedly retained in a suitable .window-'frame 9, the latter alsopreferably of hollow sheet metal construction of a type for Whichwe havemade separate application for patent'.-

In the form of our device shown in Fig. 3, used asparting strips for thepanes 5 of a window, the arm 4C is shortened and open and arms 4A and 4Dare laidagainst the adjacent panes 5 with arm 4C laid between the panesand protruding beyond the oppo-` site sides Vof the latter. Theseprotruding edges of arm 4C are engaged and covered by another auxiliaryhollow strip 11- also made of sheet iron and T-shaped in cross section,the leg of the T designated as y11A and the arms as 11B and 11C, thelatter arms adapted to be laid against the glass opposite to member 4and having a slotted part between the adjacent parts of arms 11B and 11Cwhich loosely engage the outer sides of the protruding part of arm 4C.Then machine screws 7 or the like are passed diagonally through (bothways) the central part of both members 4and 11 to hold the Oppositestrips tight against opposite sides of the lass. Y

The preferred form of our device (star shaped in cross section) is alsoshown in Fig. 5 in enlarged scale and used as the vertical members of adoor frame and the arms in various lengths. vArm 4A is long and adaptedto be imbedded in mortar 12 between bricks 13 of a wall. Arms 4Carecoinparatively long and to one of them is suitably xed the Wings of anysuitable number of hinges 14 the other wings of which are suitablysecured as at 15 to a door 16. The hinge edge of such door 16 may begrooved ook to fit snugly as at 16A over arm`4D and thus Closed. l 'Y"vfl'sfwon-whi'ch rheihinges ofthe, door 16 ndfthe storxnfonscreenedzdool 1655sA se- A I nealframe bar foyy Windows, doofe andche'llkeJ compljlslng sheet metal tubular though leadi mayensecl attheeclgesof. l
